My invention has reference to a grain bin or crib, and is designed for use in storing large quantities of corn in the ear, shelled corn, or other grains. Its chief purpose is s to provide a storage place for the grain in which it will be preserved not only from heating or rotting, or being subject to other conditions to which grain in the bin is usually liable, but in which it also will be preis served from rodents or other vermin.

for getting into the grain.

Another purpose of the invention is to provide means for making it possible to determine at any timethe height of the grain in the bin. A convenient means is also pro- .25 vided for starting the removal of the grain from the bin. I

The above named and other features and advantages of the invention will be more fully understood from the following speci- -e0 fication, reference being had to the drawings accompanying the same, in which;

Fig. l is an elevation of a crib which embodies the invention. I

Fig. 2 is a vertical medial section thereof.

Fig. 3 is a horizontal cross-section through the body of the crib.

Fig. a is a detail of one of the sections 4, with the top plate removed.

rig. is a detail of the shoveling chamher 20, partly in section.

The invention is formed throughout of metal, and consists of an outer wall 1, preferably of a circular form, and an inner cylinder 2 spaced therefrom, and formed of wire netting or similar material. At intevals the walls 1 and 2 are united by posts 3, and fixed to the lower edge of the wall 2 is an angle-plate circle 3' the flange of which projects inwardly and rests upon the 5o outer edge of a base formed of sections 4,

througliiwhich opening thegrain may be introduced into the crib, asby a grain elevator. The centralopeningin theroof is provided with a ventilator cap 14.

5, and 6, said sections tapering toward .the center of the base. Said sections ,arepreferably formed of tile, and passages 7 connect'the outer sides thereof with a .central space 8; The passages 7 also communicate at their outer ends with thespace between the walls land 2.

Extending upwardly from the space 8. is acylindrical ventilator 9,'supported on the basesections -6'by a collar 10 fixed to said ventilator. The upper end of' the-ventilator connects with a-central opening in a roof- 11, therouter edges of which project beyond the walls l. Thevehtilator- 9 is also formed of aiwiremesh of suitable sizeand strength, and it is'reinforced 'by a wirecoil 12. At one sidethe roof 11 is provided with an opening, normally closed by aitrap door .13,

lVhen the receptacle is supplied with grain, as indicated at A in ,Eig. 32 the .venti- .lator torms a ch mneylthrough gw h ch a cur rent; of air. passes upwardly and outwardly,

The venti'lators laare made to fit tightly'between tlieventilator l and "wall 2, and they areflinstalled by laying the same on theto'p of the grain after it has attained to a desired height. After thergraiir reaches to a height "to eover the ventilators :15 they 2 form laterals between the central-chimney and the outer. space between the walls, and assist '1n-,-caus1ng a thorough circulation 1 of 1a i uteue he. "rai .A manye t of h lateral ventilators can be providedas may be desired,,,andany number -of;tl1e ventilawrs-prqv dadto ch They a a solb arrang d pi a y i de It will" be noted that any rodent which may enter the cribythrough the passages in base will merely pass upwardly through the air passages connecting with said central cylcent-ral chimney and out at the top,

that happens to get in at the top will pass ta downwardly and out at the bottom, without any possibility of getting into the grain. The grain is also stored at a point above the ground, so that moisture cannot enter the same, and the floors of the passages 7 are formed so as to slope outwardly, preventing the water from finding its way into the center. If desired, a foundation of concrete or other suitable material may be provided for the base of the crib to rest on. The forming of the base in sections also makes it possible to transport the crib and base from one place to another, or store the same.

In Fig. 1 the outer wall is shown provided with a netting section 16, through which the interior of the crib may be viewed, to deter- I mine the height of the grain therein. Said netting section is normally closed by a door 17, rollingly supported. An opening 18 is also provided in the wall 1, the upper part of which is closed by removable doors 19, and in the lower part is installed a shoveling chamber 20, opening to the interior of the crib, and having inclined ways 21, in

which is slidable a gate 22. When it is desired to remove some of the grain the gate 22 is raised a little and the grain permitted to run out into the chamber 20, from which it can be shovelled. As more of the grain is removed, and it is desired to enter the crib, the doors 19 are removed, permitting free access to the interior. The opening 18 is normally closed by a door 23, also rollingly supported, so as to be easily moved to one side, as shown.

' One of the sections 4 is shown in Fig. 4, the same being provided with a central rib 24 for strength. The sections 5 and 6 can be similarly reinforced.

What I claim, and desire to secure by Letters Patent, is:

1. A crib for grain, comprising an outer metal casing and roof therefor, having a central opening, a recticulate wire container within said casing and spaced therefrom, a hollow base for said crib having air intake passages and a central opening therefor, said passages communicating wit-h the space between said casing and said container, a reinforced wire net-Work cylinder extending from said opening in the base to the opening in the roof, and lateral wire net-work cylinders extending from said first-named cylinder to the wall of said container, said cylinders forming air-ducts when the container is provided with a supply of grain.

2. In a device of the class described, an outer enclosure, an inner net-work container spaced from the outer enclosure, a central wire mesh cylinder and radial wire mesh cylinders connected therewith, and enclosed or one inder and with the space between said coniner and said enclosure. In testimony whereof I afiix my signature.
